摘要： A header for an agricultural vehicle. The header includes a header frame and an elongate sickle knife mounted along a leading edge of the header. The header further includes an actuator for reciprocally moving the elongate sickle knife in its longitudinal direction relative to the header frame between a first position and a second position over an intermediate position. At least one accumulator extends between the header frame and the elongate sickle knife to accumulate energy during a first movement of the elongate sickle knife from the intermediate position towards at least one of the first position and the second position, and to release accumulated energy during a second movement of the elongate sickle knife opposite to the first movement.

摘要： The knife head mounts to the sickle to hold a plurality of knife sections thereon while allowing removal of the knife sections individually without major disassembly for ease of in field repair and replacement. A knife pin of the knife head connects to a knife arm driven by the sickle drive mechanism and is removable from above also without major disassembly. The knife pin connection provides a vertical self adjustment capability to accommodate sickle wear and vertical misalignment between the sickle and drive. And the knife arm is streamlined for cut plant material flow thereabout and is also adapted for ease of removal and field repair.

摘要： An agricultural cutting device has knife bar sections with section knife blades. A drive with phase offset drives the knife bar sections at least temporarily in opposite directions. The section knife blades interact scissor-like with counter knives. The knife bar sections have adjacently positioned bar ends. When the knife bar sections move, a gap of varying size is formed between the bar ends. A mowing finger is arranged at the gap. A stationary knife blade with first cutting edges is arranged at the mowing finger. The first cutting edges are arranged adjacent to the mowing finger and extend at a slant relative to a forward travel direction of the cutting device so that the cutting edges have a V-shaped arrangement broadening in travel direction. The knife bar sections have an outer knife blade attached to the bar ends whose cutting edges extend parallel to the travel direction.

摘要： In a sickle cutting system, it has been found that a significant decrease in cutting inefficiency, which is measured by calculating the area of the cutting process where crop is not immediately cut but is instead pushed forwardly by engagement with a surface of the system, can be obtained by a combination of one or more of the features where the cutting stroke is reduced from the conventional length of 3.0 inches to a value of the order of 2.0 inches; the length of the cutting edge of each knife blade is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.0 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex.
